Maternal/Child I

QuestionAnswer
Normal temperature range for newborns 36.5-36 axillary (crying may elevate temperature) (stabilizes 8-10 hrs after delivery)
Normal HR range for newborns 120-160 B/M (can go as low as 100 when sleeping to 180 when crying) (rate may be irregular with crying) (faint-sounding heartbeat is sign of potential distressed)
Normal respiration range for newborns 30-60 breaths per minute (moist breath sounds may be present shortly after birth) be concerned if: apnea > 15 sec, diminished sounds, grunting, nasal flaring, deep sighing, persistent irreg breathing, excess mucus, persistent fine crackles, stridor
Normal range for head circumference measurement for newborns 33 to 35 cm (should be 2 to 3 cms larger than the chest) (molding of head may result in a lower measurement)
Normal range for chest circumference for newborns 30.5-33 cm (head and chest measurements may be equal for the first 24 to 48 hours of life)
Normal weight range for newborns 2500 - 4000 gms
Normal length range for newborns 48 to 53 cms
Kick Counts test Mother lies on left side and counts fetal kicks for period of time (usually 1 hr). Pt calls provider or goes to hospital if baby not moving as much as indicated by provider.
Nonstress Test Assess placental function/ oxygenation, indicator of fetal well being. Normal (reactive): 2 or more FHR accelerations of at least 15 bpm, lasting at least 15 sec. in 20 min. Abnormal (nonreactive): No accel. or <15 bpm or lasting < 15 sec occur in 40 min
Contraction stress test Determines if fetus can tolerate labor. Is exposed to contractions to assess placental O2 perfusion during simulated labor conditions. 20-30 min strip w/fetal monitor. Uterus stimulated w/oxytocin or nipple stim. until 3 contractions >or= 40 sec in 10 min
Normal Contraction stress test result Would be negative result. 3 contractions lasting 40 sec in 10 min w/o evidence of late decelerations of FHR
Abnormal Contraction Stress Test Result + result. Late or variable decelerations of FHR w/ @ least 50% or more of the contraxns in the absence of hyperstim. of uterus. Suspicious result: nonpersistent late decels or decels associated w/hyperstim (i.e. contractions q 2 min or last > 90 sec)
Biophysical Profile (BPP) Score on 5 criteria (ultrasound): breathing movements, body ", muscle tone, FHR reactivity & amniotic fluid vol. Normal: 8-10, Need for delivery: < 4
When/why is an amniocentesis performed? 2nd trimester: chromosome analysis. 3rd trimester: r/o infection or verify fetal lung maturity
Potential risks related r/t amniocentesis maternal hemorrhage, infection, Rh isoimmuniztion, abruptioplacentae, amniotic fluid emboli, premature rupture of membranes. Notify HCP: chills, fever, leakage @ insertion site, decreased fetal movement, uterine contractions
Fetal period Beginning of 9th wk until birth. Rapid growth and differentiation of tissues, organs, systems. Less vulnerable than embryonic period.
Vessels in umbilical cord One vein, two arteries.
Wharton's Jelly Protects umbilical cord from compression
Placental hormones Human Chorionic Gonadotrophin, Human Placental Lactogen, Progesterone, Estrogen
Amnion vs chorion in the embryo Amnion: inner membrane, contains amniotic fluid Chorion: Outer membrane, forms fetal portion of placenta
Fetal heart begins to beat by _________ week End of third week
Umbilical vein Blood from placenta to fetus
Ductus venosus Allows fetal circulation to bypass of the liver in utero, opening allows blood pass from umbilical vein to superior vena cava
Foramen ovale Opening in fetal heart between atria, which allows blood to bypass the lungs, so that most of the oxygenated blood goes to the brain first
Ductus arteriosus Opening in fetal pulmonary artery directly into aorta, so blood can bypass lungs (is already oxygenated) and head straight to the brain
Mom should be feeling fetal movement by week 17
Fetus starts to produce surfactant by week ___________ 24
Fetal lungs generally developed by week _________ 36
Fetus considered potentially viable at week ________ 26
Monozygotic twins Identical twins. Does not run in families, the division of the zygote is a coincidence, which occurs by the end of the first week.
Dizygotic twins fraternal twins. Can run in families, due to hyperovulation
Neonatal hypoglycemia <40-45. s&s: jitteriness, resp distress, poor suck, low temp, lethargy or diabetic mother BG
By 2 hrs of age, the newborn should: Be awake, meet mom and dad. Breathe unassisted. Maintain temp w/in normal range. Eat (breast w/in 1st hr). Sleep after 1st period of reactivity. Void or have meconium stool by 24 hrs.
Baby considered preterm if delivered at < _________ wks 37
Baby postterm if delivered > ____ weeks 42
